组件式机械仿真流程建模平台的设计与实现

在具体分析WFMC规范基础上,结合组件开发思想,采用Java语言,利用EMF和GEF技术,根据仿真流程实际需要抽象成仿真组件,实现了组件式机械仿真流程建模平台,并简要介绍了流程在执行期间的状态表示机制.根据抽象出的13个静力学仿真组件,利用此建模平台完成了针对机械产品静力学仿真流程模型的建立,并从语法上对流程进行了有效性检验,证明了平台的适用性和灵活性.

Design and implementation of component mechanical workflow modeling platform

The existence of various CAE engineering software improves the simulation efficency. And in the simulation process of mechanical product, the integration of function modules of various engineering software is the key problem to realize simulation task flow. Based on the analyzing of WFMC criterion, with the thought of component development which improves the flexible and extensible of system, abstract simulation component through the reality need, a component based simulation workflow modeling platform is implemented, by using EMF, GEF technologies and Java language, and the status-express mechanism in process executing is briefly introduced. Finally, static simulation flow model of a mechanical product is built with the platform, and its validity is verified on syntax. The result proves the applicability and agility of the modeling platform.
